EXECUTIVE SUMMARY
ES 1. INTRODUCTION
In 2009, the Connecticut Department of Energy and Environmental Protection (DEEP) sponsored an inaugural statewide waste characterization study, the results of which were published in 2010 (2010 Study). This report contains the results of the 2015 Statewide Waste Characterization Study (2015 Study).
The 2015 Study sought to duplicate the methodology of the 2010 Study so that changes in the disposed waste stream could be measured and so that results could inform DEEP’s imminent update of the State Solid Waste Management Plan. Accordingly, the 2015 Study captured random samples of wastes from Residential and Industrial/Commercial/Institutional (ICI) generators delivered to five solid waste facilities across the State, including the same four Energy-from-Waste facilities and one transfer station as were captured in the 2010 Study. Additionally, DEEP expanded the 2015 Study scope to include additional sampling and sorting of single stream recyclables at two Material Recovery Facilities (MRFs), as well as targeted sampling of wastes from six specific ICI generator types.
ES 2. RESULTS – WASTE CHARACTERIZATION
ES 2.1. STATEWIDE WASTE COMPOSITION
Figure ES 2-1 shows the composition and tonnage of disposed wastes in 2015, aggregating the Residential and ICI generator sectors. As shown, Paper and Food Waste are the most common material groups.
Figure ES 2-1 Municipal Solid Waste Composition and Quantities Disposed (tons)
Figure ES 2-2 compares the composition in 2015 with the same result from the 2010 Study. The most noteworthy change in the waste stream since 2010 is the heightened fraction of Food Waste remaining in disposed wastes, along with relatively lower incidence of most other materials. It should be noted that when data are presented in percentages, a significant change in the percent of one fraction of the waste stream automatically results in a change in the percentages of all other materials. For example, the large increase in food waste drives down the percentage composition of other materials.

EXECUTIVE SUMMARY
CT DEEP ES-3
The above figure highlights a number of important findings about Connecticut’s disposed wastes:
The fraction of targeted curbside recyclables – dry fiber and plastic, metal and glass containers – remaining in the waste stream is a relatively small piece of the pie at a combined 15.9 percent.
Compostable organics – which include food wastes, green wastes, and some compostable papers – are quite significant at 41.4 percent. However, it is important to note that these materials may not be easily source-separated prior to disposal, nor separated from disposed wastes such that they could be recovered for feedstock in a plant designed to manage organic wastes.
Even with significantly enhanced capture of targeted fiber, recyclable containers, and organics, over 41 percent of the disposed waste stream is not readily recyclable in existing curbside (or on-site commercial) recycling programs without:
Adding materials to the existing programs
Making better use of other outlets for diverting materials (home composting, scrap metal recyclers, reuse stores, etc.)
Adding new recycling programs possibly in conjunction with development of local markets to accept such materials
It is also critical to note that the above figure represents the rosiest possible definition of what is “recoverable” in existing programs. To perform this study, manual sorters were trained to separate all items for placement in the correct category, and did not make any adjustments for contamination of sorted materials, nor the ability of a mechanical processing system to accurately separate such materials for recovery. The results of this exercise can be considered an “academic” characterization of the waste stream. Many of the recyclable and compostable organic items would never be recovered or diverted because of contamination, or because they are so intermingled with non-recoverable items prior to placement in the waste receptacle (or as a result of the collection process) that no processing line could economically separate and recover the item.
ES 2.2. WASTE COMPOSITION BY GENERATOR SECTOR
Figure ES 2-4 compares the percentage composition of material groups for Residential and ICI waste. On a percentage basis, it is shown that ICI waste contains a higher incidence of Paper and Food Waste, while the Residential sector disposes a higher percentage of Other Organics (which include yard debris and diapers) and Other Wastes.

EXECUTIVE SUMMARY
CT DEEP ES-5
Figure ES 2-6 shows the top 10 most prevalent materials in the MSW stream in both the 2010 and 2015 Studies. As shown, the most prevalent material in both studies was Food Waste and Compostable Paper, although the incidence of both has increased in 2015.
Figure ES 2-6 Comparison of 2015 and 2010 Top 10 Materials
The 2015 Study also provides composition data from samples generated in Urban, Suburban and Rural areas of Connecticut. Ultimately, 192 out of 235 total samples originated in Urban areas, so the results of the 2015 Study should be considered to be more heavily weighted towards these areas. Future studies may seek to capture more samples from Suburban and Rural areas of the state.
Finally, the body of this report contains results individually for the five disposal facilities that hosted field data collection.
ES 3. RESULTS – SINGLE STREAM RECYCLING COMPOSITION
Single stream recyclables were sampled at two Material Recovery Facilities (MRFs). In the initial sort, any material contained in plastic bags was considered to be a contaminant. However, the bagged wastes were set aside and sorted, and the composition of single stream recyclables was re-calculated as if Bagged Wastes were allowable as targeted recyclables.
Figure ES 3-1 illustrates the breakdown of recyclable paper (blue), recyclable containers and plastics (green) and contamination (red) in single stream recycling, with Bagged Waste considered to be a contaminant. Recyclable containers comprise just over 27 percent of the total, with glass bottles (including broken glass) the most prevalent container type by weight.

Figure ES 3-1 Single-Stream Recycling Composition (Bagged Waste as Contaminant)
The Bagged Wastes were subsequently analyzed to determine what materials are arriving at single stream MRFs still contained in bags. Figure ES 3-2 shows the incidence of both targeted recyclables and contaminants in Bagged Wastes. As shown, Bagged Wastes were found to be roughly split between trash and recyclables. In practice, some bags contained mostly or entirely recyclables, while other contained mostly or entirely trash. Other bags contained a mix.
Figure ES 3-2 Composition of Bagged Waste Arriving in Single Stream Loads
If Bagged Wastes are treated as targeted recyclables, the contamination rate is reduced marginally (because recyclable material contained in the bags are captured in the calculation). Figure ES 3-3 restates the breakdown of single stream recyclables to reflect the impact of breaking open and sorting Bagged Wastes into the appropriate recyclable paper, recyclable containers/plastics, or contamination category. As shown, the overall contamination rate drops slightly to 16.7 percent (with bagged newspaper still considered

1. INTRODUCTION
1.1 BACKGROUND
In 2009, the Connecticut Department of Energy and Environmental Protection (DEEP) sponsored an inaugural statewide waste characterization study to measure the composition of Residential and Industrial/Commercial/Institutional (ICI) municipal solid waste (MSW or “waste”) disposed within the State. The results of this study were published in 2010 (2010 Study) and have been used by DEEP and other recycling and waste management program managers, planners, and businesses across Connecticut.
DEEP commissioned the 2015 Statewide Waste Characterization Study (2015 Study) to follow the same methodology as was used in the 2010 Study. The 2015 Study sought to duplicate the methodology of the 2010 Study so that changes in the disposed waste stream could be measured and so that results could inform DEEP’s imminent update of the State Solid Waste Management Plan. Additionally, DEEP expanded the 2015 Study scope to include additional sampling and sorting of single stream recyclables at two Material Recovery Facilities (MRFs), as well as targeted sampling of wastes from six specific ICI generators.
1.2 PROJECT TEAM
In 2015, DEEP retained the Project Team of MSW Consultants, LLC, DSM Environmental Services, Inc. (DSM), and Cascadia Consulting Group (Cascadia) to complete a statistically representative update and analysis of Connecticut’s disposed waste stream. This Project Team also performed the 2010 Study and was consequently able to assure high continuity of the data collection methods and analysis performed. The roles and responsibilities of each Team member are summarized:
MSW Consultants coordinated the Project Team in all activities and had primary responsibility for:
Project Management,
Client Contact,
Preparation of Study Design,
Problem Resolution,
Field Supervision,
On-site Logistics,
Sample Selection, Collection, and Sorting,
Training of Sort Crew,
Sorting QA/QC,
Compilation of Sorting Data,
Preparation of the Interim Report,
Preparation of the Draft and Final Report.
DSM was responsible for:
Site Selection Logistics,
Performance and Analysis of Hauler Surveys to Determine the Residential/ICI Split,
ICI Special Generator Sampling Plan and Sample Acquisition,
Monitoring Dedicated Commercial Routes for Generator Samples,
Review of Interim Report,
Review of Draft and Final Report.

1.3 COMPARISON TO 2010 STUDY
From the outset, it was the intent of DEEP that the 2015 Study be performed so that the results could be closely compared to the 2010 Study results. In particular, the 2015 Study attempted to follow the 2010 Study methodology to the greatest degree possible. The more closely the 2010 Study methodology could be duplicated, the fewer the number of variables there are that may create differences in results between the two Studies.
This section identifies the similarities and differences between the methodologies used in 2010 and 2015. As shown, most aspects of the field data collection methodology were identical in both studies. Additionally, the 2015 Study was expanded to include three new initiatives that were not performed in 2010. Similarities and differences (including the new initiatives) are described below and addressed in greater detail in the body of the report.
1.3.1 SIMILARITIES BETWEEN STUDIES
Host Facilities: Both the 2010 and 2015 Study performed sampling and sorting at the same host disposal facilities:
Bristol Resource Recovery Facility (RRF),
Materials Innovation and Recycling Authority (MIRA) Hartford RRF,
Covanta-Preston RRF,
New Haven Municipal Transfer Station,
Wheelabrator-Bridgeport RRF.
Definitions of Waste Sectors: The 2010 and 2015 Studies retained the same two generator sectors: Residential and Institutional/Commercial/Industrial (ICI). Both studies omitted inbound loads that were found to be less than 80 percent pure Residential or ICI. This included all transfer trailer loads because the mix of residential and ICI waste could not be determined.
Obtaining Samples from Inbound Trucks: Both studies relied on systematic sampling protocols to select vehicle for sampling and sorting. Both studies used random grab sampling (assisted by loader operators at each host facility) to obtain materials from the tipped load for sorting.
Sample Weights: Both studies targeted samples between 200 and 250 pounds.
Material Categories: Material categories were substantially identical between the studies. The following minor modifications were incorporated in the 2015 Study:
Aseptic boxes and gable top cartons were added as a new category,
Food waste still contained in packaging was added as a new category to be differentiated from food wastes disposed loose in the waste stream,
Flexible (film) plastic packaging (including pouches) was added as a new category,
Diapers and sanitary products were added as a new category, and
Offshore Cardboard was consolidated into the Old Corrugated Cardboard category.
1. INTRODUCTION
CT - DEEP 1-3
Determination of the Statewide Residential/ICI Split: In both the 2010 and 2015 Studies, the Project Team performed two days of gate surveys at each host disposal facility to characterize inbound wastes by generator sector. The results of the gate survey were used in both studies to allocate statewide waste disposal between residential generators and ICI generators.
1.3.2 DIFFERENCES BETWEEN THE STUDIES
Seasonality of Data Collection: Field data collection occurred over two seasons in both Studies. However, the 2010 Study observed a more rigorous definition of the winter and fall seasons, collecting data in February-March and October 2009, respectively. Each host facility was sampled once per season in 2009. The 2015 Study also divided data collection into two separate events. The first season was performed over May and June 2015 and represented the spring season. The second season was performed in August and September 2015, reflecting the summer season. Sampling and sorting occurred in both seasons at four of the five host facilities in 2015. Due to factors beyond the control of the Project Team, field data collection was only performed during the summer season at the MIRA Hartford RRF.
Characterization of Wastes by Demographic Region: For most of the samples obtained in the 2015 Study, the Project Team recorded the city or town from which the wastes originated. With input from DEEP, all Connecticut cities and towns were characterized as being urban, suburban, or rural. The 2015 Study consequently estimates disposed waste composition from urban, suburban and rural areas of the state. No comparable results were developed in the 2010 Study.
Characterization of Wastes from Targeted ICI Generator Sectors: The 2015 Study was expanded to allow for additional, targeted analysis of the composition of disposed wastes from six ICI generator sectors. No such generator sector-specific analysis was performed in 2010. The ICI generator sectors targeted in the 2015 Study were:
Grocery,
Restaurant,
Hotel,
Retail – Big Box,
Retail – Small, and
Offices.
Single Stream Recycling Composition Study: The 2015 Study was also expanded to include composition analysis of single stream residential recyclables at two Material Recovery Facilities (MRFs). DEEP and the Project Team believe this is the most comprehensive analysis undertaken by a public entity of single stream recycling to take place in Connecticut to date. The single stream recycling composition analysis was designed to capture a representative sample of residentially generated single stream materials, which were sorted into substantially the same categories as the disposed waste composition analysis. However, the single stream composition analysis utilized several condensed categories of non-targeted materials, as well as several new categories relevant to MRF operators. No composition analysis was performed on single stream recyclables in 2010. The following MRFs hosted single stream composition analysis in the 2015 Study:
MIRA Hartford Regional Recycling Center, and
Willimantic Waste & Recycling Center, Willimantic.

2.2 WASTE TYPES AND GENERATOR SECTORS
2.2.1 DISPOSED WASTE
Consistent with the 2010 Study, the 2015 Study targeted disposed wastes from the following two generator sectors:
Residential: defined as waste brought to CT DEEP facilities by commercially or municipally operated vehicles, in which 80% or more of the waste was from single-family and/or multifamily residential sources. Vehicles chosen for sampling in the Residential waste sector included Residential Transfer Trucks arriving from rural transfer stations as well as Packer Trucks carrying waste from single family routes.
Institutional/Commercial/Industrial (ICI): defined as waste brought to CT DEEP facilities by commercially operated vehicles, in which 80% or more of the waste was from institutional, commercial, or industrial sources. This sector excluded Construction and Demolition (C&D) debris as well as Bulky Waste. Vehicles chosen for sampling in the ICI sector included Compacted Dropboxes and Packer Trucks.
It should be noted that inbound loads containing less than 80% of either residential or ICI waste, and loads originating from outside of Connecticut, were excluded from the study. It is also important to note that neither the 2010 nor 2015 Studies targeted Bulky Wastes from the residential and ICI waste streams. Although some Bulky Wastes are delivered to the disposal facilities that hosted this study, Bulky Wastes are often non-processible at RRFs, and are more typically managed at Volume Reduction Facilities (VRFs) with construction and demolition (C&D) debris. Bulky wastes (and C&D debris) were excluded from this study.
2.2.2 ICI GENERATOR SAMPLING
The 2015 Study targeted six specific ICI generator types for sampling and sorting. These samples were obtained from trucks that were identified via driver interview and not obtained at random, and in many cases were specially arranged for delivery by a local hauler. The targeted commercial generator types in the 2015 Study are:
Grocery,
Restaurant,
Hotel,
Retail-Big Box,
Retail-Small, and
Offices.
This effort was new in the 2015 Study and was not performed in the 2010 Study.
2.2.3 SINGLE STREAM RECYCLABLES
Only residentially generated recyclables were targeted for the composition analysis of single stream materials. This is important to note because many MRFs process recyclables from both residential and ICI generators, and consequently the results of the residential single stream composition analysis may not be representative of a MRF’s plant-wide recovered commodity and residue rates (which include both residential and ICI recyclables mixed together during processing).
2.3 FIELD DATA COLLECTION SCHEDULE
Table 2-2 summarizes the field data collection schedule for the 2015 Study. As shown, data were collected over two seasons, representative of spring (May-June) and summer (August-September). Conversely, the 2010 Study obtained field data in winter (February-March) and fall (October).

[1] The first season sort at MIRA WTF (Hartford) was canceled because of a shortage of space on the tip floor
to conduct sorting activities.
[2] The original study design called for sorting at one MRF each season. Unforeseen schedule changes to the
disposed waste sorting caused sorting at the MIRA MRF to be spread over two seasons.
2.4 STATEWIDE DISPOSED WASTE AND RECYCLED MATERIAL
QUANTITIES
2.4.1 OVERALL
DEEP tracks the flow of wastes generated in the state. Table 2-3 provides the reported annual statewide waste disposed in Connecticut as cited in this and the 2010 Study. As shown, disposed waste quantities have remained virtually unchanged.
Table 2-3 Disposed Wastes, 2015 and 2010 Studies
Data Point 2015 Study 2010 Study
Statewide Waste Disposal 2,332,598 tons 2,379,687 tons
Year of Reported Disposal Data FY2013 CY2009
Statewide estimates of the disposed waste composition include both percentages and tons based on the data in Table 2-3.
It was not within the scope of this study to attempt to estimate the statewide quantity of residentially generated recyclables, and consequently composition results for single stream materials do not include quantities, only percentages. Due to lack of data availability, it also was beyond the scope of this study to apply the composition percentages for other results sets to disposal tonnages.
2.4.2 RESIDENTIAL VS ICI BREAKDOWN
At the current time, there are no routinely reported data to indicate the fraction of disposed wastes originating from Residential and ICI sources. In order to determine a reasonable estimate, the 2015 Study, like the 2010 Study, included a survey of incoming trucks at each of the host disposal facilities to assess this split (hauler survey).
The purpose of the hauler survey was to provide a basis for allocating total mixed solid waste tons disposed in Connecticut, as provided by CT DEEP, between residential and ICI wastes so that the percent composition of each waste stream determined by hand sorting could be applied to total tons by generator type at the state level. The following two rounds of hauler surveys, roughly corresponding to the two season hand sorting, were completed.
2. METHODOLOGY
2-4 CT - DEEP
Season 1 (Spring Season) of Hauler Surveys began on Wednesday, May 13, 2015 and finished on Wednesday, June 10, 2015. Team member DSM Environmental Services, Inc. (DSM) carried out one day of hauler surveys at each of the five facilities participating in the waste composition study, resulting in 272 completed surveys. The number of completed surveys at some participating facilities were limited due to the fullness of tipping floors, resulting in less truck traffic and longer wait times to enter the tipping floor.
Season 2 (Summer Season) of Hauler Surveys started on Monday, August 24, 2015 and finished on Tuesday, September 28, 2015. As was the case during Season 1, DSM carried out one day of hauler surveys at each of the facilities participating in the waste composition study, resulting in 278 completed hauler surveys. The number of completed surveys was more evenly split among participating facilities because the tipping floors were not as full as seen in Season 1.
Surveys were not carried out on transfer trailers, dump trucks, or private vehicles; only on roll-offs and packer trucks carrying municipal solid waste (MSW). Loads containing bulky waste, C&D debris, or ‘other waste’ were eliminated from completed surveys because hand sorting did not include bulky waste loads or C&D wastes, and therefore the MSW allocation is for residential and ICI waste only.
The following bullets describe the surveying carried out at each host disposal facility:
Wheelabrator Bridgeport RRF: Season 1 hauler surveys were performed on Wednesday, May 13, 2015 at the Bridgeport facility resulting in 26 hauler surveys. Season 2 had 42 completed hauler surveys at the Bridgeport facility during the afternoon of Monday, September 21, 2015 and the morning of Tuesday, September 22, 2015 resulting in one full surveying day. Season 1 drivers reported waiting two to four hours to tip due to the fullness of the tipping floor. The limited number of Season 1 hauler surveys reflect the full tipping floor and the lack of trucks entering the facility that were not transfer trailers. Season 2 saw an increase in hauler surveys with a decrease in average wait times.
New Haven Municipal Transfer Station: A total of 24 hauler surveys were obtained during Season 1 at the New Haven Municipal Transfer Station on Thursday, May 14, 2015 and 24 hauler surveys during Season 2 on Thursday, August 27, 2015. Season 1 surveys included ‘Bulky’ waste coming in from dormitory cleanouts at Yale University; these surveys were ultimately excluded from the analysis. Drivers did not have to wait to tip at the New Haven Municipal Transfer Station and it appeared that the tipping floor was not full. The majority of haulers using the New Haven Municipal Transfer Station were from the City of New Haven, or private haulers that service the Yale University campus.
MIRA Connecticut Mid-Connecticut (Hartford) RRF: A total of 112 hauler surveys were obtained during Season 1 at the MIRA Connecticut Solid Waste System (Hartford) RRF on Thursday, June 4, 2015 and 75 driver surveys during Season 2 on August 26, 2015. The day prior to surveying for Season 1, MIRA had stopped accepting trucks in the early afternoon to ‘catch up’ with the amount of waste on the tipping floor. Due to this early closure they were able to accept more trucks at a lower wait time on the day the survey took place. The number of surveys completed at MIRA Hartford during Season 2 may reflect a more typical delivery day at the facility
Bristol RRF: Forty-three (43) hauler surveys were obtained during Season 1 at the Bristol RRF on Friday, June 5, 2014 and 59 surveys during Season 2 on Monday, August 24, 2015. During Season 1 drivers were reporting a wait time upwards of five hours due to the fullness of the tipping room floor. Season 2 saw significantly decreased wait times for drivers, and an increase in truck surveys.
Covanta Preston RRF – Two partial days of hauler surveys were performed at the Covanta (Preston) facility during Season 1 on Tuesday, June 9, 2015 and Wednesday, June 10, 2015 resulting in a total of 67 hauler surveys; and 78 hauler surveys at Covanta (Preston) on Monday, September 28th, 2015 during Season 2. Preston did not see a significant change in wait times, or completed surveys between Season 1 and Season 2.
2. METHODOLOGY

For the surveys, each hauler’s truck number was matched with the corresponding weight ticket so that the surveys could be tabulated by tonnage rather than number of loads observed. Table 2-4 provides the results of the hauler surveys.

Covanta, Preston RRF 145 979 22.3% 54.5% 45.5%
Total 550 4,397 100% 58.4% 41.6%
As presented in Table 2-4, truck surveys at MIRA, Mid-Connecticut (Hartford) RRF represent 36 percent of total truck tons captured during the surveys, with the next closest facility (Covanta, Preston RRF) representing another 22 percent. Combined, these two facilities represent 58 percent of the total truck tons surveyed, somewhat influencing the residential versus commercial allocation. As illustrated by Table 2-4, with the exception of the Bristol RRF, all of the participating facilities had an incoming residential percentage (excluding transfer trailer waste) between 51% and 59% and a commercial percentage between 41% and 49%.
It should be noted that the statewide allocation found in the 2010 Study 56%/44% residential/ICI, compared to the 58%/42% found in 2015. These results suggest that the mix of Residential and ICI wastes at these five host facilities have remained relatively consistent since the 2010 Study.
However, as cautioned in the 2010 waste characterization report, the above allocation is based on truck surveys of waste delivered to in-state facilities, many of which have contracts with municipalities. Because municipalities control primarily residential waste, it is likely that the hauler surveys at these facilities under-represent ICI waste. As such, the waste composition results may be influenced by decisions of haulers to haul certain wastes to in-state facilities and transfer other waste to out-of-state facilities. This is an unknown variable that could influence the state-wide results. Therefore it is important to keep in mind in reviewing the data in this report that it is statistically representative of waste delivered to the host facilities, and that we have extrapolated these data to total tons disposed in-state, ignoring waste delivered out-of-state.
2.4.3 DISPOSAL QUANTITIES BY DEMOGRAPHIC REGION
At the request of DEEP, the 2015 Study sought to differentiate waste composition from urban, suburban and rural areas of the State. The U.S. Census Bureau classifies as “Urban” all territory, population, and housing units located within urbanized areas (UAs) and urban clusters (UCs). It delineates UA and UC boundaries to encompass densely settled territory, which generally consists of:
A cluster of one or more block groups or census blocks each of which has a population density of at least 1,000 people per square mile at the time, and
Surrounding block groups and census blocks each of which has a population density of at least 500 people per square mile at the time, and
Less densely settled blocks that form enclaves or indentations, or are used to connect dis-contiguous areas with qualifying densities.
2. METHODOLOGY
2-6 CT - DEEP
“Rural” has been classified as all territory, population, and housing units located outside of UAs and UCs. Geographic entities, such as metropolitan areas, counties, minor civil divisions (MCDs), and places, often contain both urban and rural territory, population, and housing units.
For the 2015 Study, DEEP classified every city and town in Connecticut as being Urban, Suburban or Rural. Table 2-5 summarizes the population, square mileage and population density of each demographic type based on the DEEP data. As shown, the majority of the state’s population resides in municipalities that meet the definition of an Urban location.

2.5 SAMPLING TARGETS
The 2015 Study targeted substantially more samples than the 2010 Study as a result of the addition of the single stream recycling and ICI generator samples. Table 2-6 summarizes the 2015 sampling targets by facility and waste type, as well as the actual number of samples obtained.

2. METHODOLOGY
CT - DEEP 2-7
As shown, the Project Team met overall sampling and sorting targets. However, the following anomalies are noted:
Difficulty Obtaining ICI Generator Samples: The Project Team’s strategy for obtaining ICI generator samples involved recruiting haulers to run special routes; or capturing targeted wastes from roll-off compactor boxes from the desired ICI sector identified during the hauler survey and random sampling. In practice, it was not possible to achieve the precise distribution of ICI generator samples as originally targeted, for the following reasons:
On more than one occasion, unforeseen schedule changes eliminated previously scheduled ICI generator routes from being delivered on a scheduled day.
Recruited haulers’ first obligation is to get their primary routes collected; and on at least one occasion, staffing shortages at the participating hauler on the day of a scheduled ICI generator route caused cancellation of the delivery.
Surprisingly, the Project Team found very few roll-off compactor boxes originating in retail big-box stores. It is not known if there are simply fewer big box stores in Connecticut that use compactor boxes (as opposed to dumpsters serviced by front loaders) or if these loads are being delivered to other disposal facilities within or outside the state.
Mis-characterized Single Stream Samples: In the first season, three of 40 single stream samples taken at MIRA Hartford Recycling Center were later found to be from commercial sources, not residential, and were omitted from the analysis. These three residential samples were made up in the second season MRF sort (at Willimantic).
No Seasonality for MIRA RRF Samples: Although not shown in Table 2-6, no sampling was performed at the MIRA RRF in the first season due to insufficient space available for obtaining samples on the facility tip floor.
To overcome the issues above, the Project Team maintained planned sampling and sorting productivity and collected additional random samples in cases where ICI generator samples could not be captured, allowing overall sampling targets to be met.
2.6 MATERIAL CATEGORIES AND GROUPS
Samples of waste were manually sorted into the same material categories as the 2010 Study, with the following exceptions:
Aseptic boxes and gable top cartons were added as a new category,
Food waste still contained in packaging was added as a new category,
Flexible (film) plastic packaging (including pouches) was added as a new category,
Diapers and sanitary products were added as a new category, and
Offshore Cardboard was consolidated into the Old Corrugated Cardboard category.
The resulting 72 material categories and detailed definitions used for the waste characterization study are shown in Table 2-7.

These material categories were condensed for the single stream recycling composition analysis. While all categories of targeted recyclables were sorted in both the refuse and recycling composition analysis, many categories that are considered “reject” or “contaminant” at a MRF were consolidated. Additionally, the categories of “Bagged Newspaper” and “Bagged Wastes” were added to the recycled material categories to account for these common contaminants at MRFs. The 46 categories used for the single stream composition analysis are included in Table 2-8.

2.7 SAMPLING METHODS
2.7.1 RANDOM SAMPLING
The Field Supervisor followed a systematic selection procedure to identify residential and ICI waste vehicles for sampling. To calculate vehicle sampling frequency for each waste sector, the Project Team established a sampling interval for each based on input from the facility scalehouse each day. Sampling intervals were determined by dividing the total expected number of loads for each sector arriving at the facility on the scheduled day – based on questions asked of each facility in the planning phase of the study – by the number of samples needed each day. The resulting number is the sampling frequency, and determined whether every third vehicle, every sixth vehicle, or every 20th vehicle is selected for sampling. This strategy is referred to as “selecting every nth vehicle” within a waste sector and subsector. A Vehicle Selection Form is shown in Appendix C. It should be noted that, during the second season, the sampling interval was informed by the results of the gate survey performed during the first season.
All vehicles entering the sampling facility were surveyed by the project Field Supervisor or at times a weighmaster in the scalehouse. Information was recorded about the vehicle type, city of origin, and waste type; and the net weight of each sampled load waste obtained.
Once a vehicle was selected for sampling, the Field Supervisor recorded the sample data and placed a Sample Placard on the vehicle’s windshield or dashboard. The Sample Placard contained a sample identification number, unique to every sample taken, that was recorded on the survey form and on the
2. METHODOLOGY
2-10 CT - DEEP
sample data sheet kept by the sorting crew. Selected loads were directed to the tipping area where a sample would be safely and accurately collected. Figure 2-2 shows a tipped load awaiting sampling.
Figure 2-2 Photograph of Tipped Load
During manual sorting, the Crew Chief would also note on the Hand-Sort Tally Sheet any unusual circumstances associated with the load or the sample. In cases where an insufficient number of vehicles were available for sampling at a disposal facility, the data collection crew would first change the nth vehicle to reduce the number between samples or make up the missing samples at a different location. This strategy could also be used when samples were missed for some other unforeseen reason. In all cases, the sampling plan would assign the frequencies of vehicles to be selected in such a way as to minimize the chance of “running out” of vehicles to represent a particular waste sector at a disposal facility.
2.7.2 GRAB SAMPLES FROM TIPPED LOADS
Selected loads of waste were tipped in the designated area at each host facility. From each selected load, one sample of waste was selected based on systematic “grab” from the load, treating the tipped load as a clock face. For example, if the tipped pile was viewed from the top as a clock face with 12:00 being the part of the load closest to the front of the truck, the first sample would be taken at the 12:00 position. Subsequent samples would be taken from 3 o’clock, 6 o’clock, and 9 o’clock. For the next four loads, the extraction point would shift to 1, 4, 7, and 10 o’clock, and so-on. This concept of systematically rotating around subsequent loads is shown in Figure 2-3.
Figure 2-3 Systematic Sampling Guide for Tipped Loads
2. METHODOLOGY
CT - DEEP 2-11
From each extraction point, the loader operator was instructed to take a grab sample. From each grab, a sample weighing at least 200 pounds was extracted from the pile and pre-weighed (to verify that the minimum sample weight had been achieved and to prevent sorting overly large samples, which would diminish sorting productivity). Pre-weighed samples were loaded into barrels for placement on the sort table, although bulky items were weighed and recorded separately (thereby eliminating the need to sort them at the sort table). Prior to sorting, a sorting crew member took a photograph of each sample, with the sample placard and identification number visible in the picture.
Depending upon the availability of host facility personnel, the Field Supervisor either collected the sample directly from the bucket of the front-end loader, or directed the sample to be dumped on a tarp or a paved surface. When collecting samples directly from the loader bucket, 35-gallon cans or carts were arranged side-by-side on a tarp, with the loader bucket positioned directly overhead. The Field Supervisor collected the sample systematically, by working from one side of the bucket to the other, emptying all of the contents from the front of the bucket to the back, until the desired sample weight was achieved. To help minimize sample collection bias, samples were collected from the loader bucket in an alternating fashion, that is, working from the left side of the bucket to the right side for one sample, and then from right to left on the next sample. A photograph of a sample in the loader bucket is shown in Figure 2-4, with a sample queued and labeled for sorting is shown in Figure 2-5.

2. METHODOLOGY
2-12 CT - DEEP
2.7.3 SPECIAL GENERATOR SAMPLES
The same methodology was used for taking samples from ICI generator loads. However, because of the need to recruit haulers to collect wastes from each generator category, the 2015 Study methodology allowed up to four samples to be obtained from a single specially-collected load.
2.7.4 SINGLE STREAM RECYCLING SAMPLES
The same methodology was used for taking samples of single stream recyclables. However, single-stream recycling samples were targeted at 150 pounds rather than 200 pounds. Also, grab sampling of single stream loads was slightly modified to capture representative material from the dense inner section of the load and the lighter exterior of the tipped load. For the single stream loads, before the grab sample was obtained, the Field Supervisor directed a loader or skid steer to cut off a cross section of the tipped load, so that the inner section and outer edges was exposed, prior to taking the grab sample. Grab samples were obtained systematically from the edge to the middle of successive cross sections.
2.8 MANUAL SORTING
2.8.1 SORTING PROCEDURE
Once each sample was acquired, the material was manually sorted into the prescribed component categories. Plastic 20-gallon bins with sealed bottoms were used to contain the separated components. A picture of a sample being sorted is shown in Figure 2-6.
Figure 2-6 Manual Sorting
Once the sample was acquired and placed on the sorting table, the material was sorted by hand into the prescribed component categories. Plastic 20-gallon bins with sealed bottoms were used to contain the separated components. Sorters were asked to specialize in certain material groups, with someone handling the paper categories, another the plastics, another the glass and metals, and so on. In this way, sorters became highly knowledgeable in a short period of time as to the definitions of individual material categories.
The Crew Chief monitored the homogeneity of the component bins as they accumulated, rejecting materials that were improperly classified. Open bins allowed the Crew Chief to see the material at all times and verify the purity of each component as it was weighed, before recording the weight into the database. The materials were sorted to particle size of 2 inches or less by hand, until no more than a
small amount of homogeneous fine material (―mixed residue‖) remained. This layer of mixed 2-inch-minus material was allocated to the appropriate categories based on the best judgment of the Crew Chief — most often a combination of Other Paper, Other Organics, or Food Waste. The overall goal was to sort each sample directly into component categories in order to reduce the amount of indistinguishable fines or miscellaneous categories.
2. METHODOLOGY
CT - DEEP 2-13
It should be noted that this sorting method also included the use of a customized, sturdy-framed sorting table that included a removable screen. The screen size was ½ inch, which allowed small particles to pass through to a tray under the screen. These particles, or fines, were swept into their own category.
2.8.2 WEIGHING SORTED SAMPLES
The Crew Chief was singularly responsible for overseeing all weighing and data recording of each manually sorted sample. Once each sample was sorted, and fines swept from the table, the weigh-out was performed. Each bin containing sorted materials from the just completed samples was carried over to the scale. Sorting laborers assisted with carrying and weighing the bins of sorted material, and the Crew Chief recorded all data.
The Crew Chief used a waste composition data sheet to record the composition weights. Each data sheet containing the sorted weights of each sample was matched up against the Field Supervisor’s sample sheet to assure accurate tracking of the samples each day. Figure 2-7 shows the scale and a weigh-out in progress.
Figure 2-7 Weigh-out
2.8.3 SORTING WET AND ORGANICS CONTAMINATED WASTE
During the sorting event, it was common to encounter materials that were contaminated or combined with organics or liquids. In such situations, the contaminating material was removed to the extent possible. All food was separated from other materials and all liquid, if beverage based, was removed from containers and placed in the food waste bin for weighing.
2.8.4 SORTING PACKAGED FOODS
For the 2015 Study, packaged food was separated from food that was loose in the sample or contained in a bag, box or other container for disposal. Packaged food included food that remained in its factory or retail packaging, including jars, cans, clamshells, flexible packaging, and any other packaging.
It should be noted that food was removed from the packaging in all cases, except when it was not practical to do so under normal sorting conditions. So, foods that could be easily emptied with the help of gravity were removed; foods that were viscous and not easily removed (e.g., peanut butter, mayonnaise) would remain in their packaging, as would all food still in its original packaging. Figure 2-8 shows packaged food from a food manufacturer (left) and loose food (right) from a grocery store load.

2.8.5 SITE MAINTENANCE AND CLEANUP
As guests at each of the host facilities, the Project Team took considerable effort to leave the work area clean and safe for subsequent operations. The sorting crew was also responsible for keeping litter to a minimum. The Project Team concluded each day of sorting operations with sufficient time to perform site clean-up. Clean-up included the following types of activities:
Organized stacking and stowing of sorting supplies in a designated location;
Removal of sorted wastes for burial or transfer (the host facility loader operator would help with this);
Sweeping and cleaning the sort area to prevent windblown litter and other situations that could attract vectors;
Removal and discard of day-use personal protective equipment and decontaminating personnel;
Checking out with the Facility Manager each day; and
Covering any unsorted samples with a tarp, to leave for manual sorting the next day.
2.9 DATA ANALYSIS
2.9.1 QA/QC PROCEDURE
The collection process followed a well-established set of quality assurance/quality control (QA/QC) strategies to ensure data accuracy and integrity. The QA/QC process involved the following procedures:
Assigning a unique combination sample number, facility of origin, date and time to each sample, and transferring that information to the tally sheet that was used to record material weights for the sample.
Encoding the type of waste load into the sample number. For example, on a particular date, samples of commercial waste would be numbered Com-1, Com-2, etc.
Using the vehicle selection form to track the numbers of each type of load obtained and sampled.
Verifying that data forms were obtained for each day the data collection crew was in the field.
Designing the data entry databases to prevent out-of-range values for vehicle and sample characteristics such as vehicle type, net weight, etc.
Random checks of computer-entered data against the paper forms, to verify that all numbers were being entered correctly, and to look for any systematic or random errors.
2. METHODOLOGY
CT - DEEP 2-15
Following each season of fieldwork, all field forms were transmitted to MSW Consultants’ office and entered into a waste composition database created specifically for the Connecticut Statewide Study. After the sample tally sheets were checked by the Field Supervisor, the data manager verified that all required data was recorded properly and also supervised the data entry process. As an additional step in quality control, an inspection of randomly selected records was carried out to monitor the accuracy of the data entry process.
2.9.2 STATISTICAL ANALYSIS
Generally, the waste composition calculations and the aggregation across groups was completed as follows. Composition estimates represented the ratio of the components’ weight to the total waste for each noted material component in a particular segment of the waste stream. They were derived by summing each component’s weight across all of the relevant samples and dividing by the sum of the total weight of waste, as shown in the following equation:
i
i
i
ij
jw
c
r
where:
c = weight of particular material component
w = sum of all component weights
for i = 1 to n
where n = number of selected samples
for j = 1 to m
where m = number of material components
The confidence interval for this estimate was derived in two steps. First, the variance around the estimate was calculated, accounting for the fact that the ratio included two random variables (the component and total sample weights). The variance of the ratio estimator equation follows:
V
n w
c r w
nr
ij j i
i

where:

(Note: the standard deviation is the square root of the variance term.)
Second, confidence intervals at the 90% confidence level were calculated for a component’s mean as follows:
r t Vj rj
where:
t = the value of the t-statistic corresponding to a 90% confidence level
2. METHODOLOGY
2-16 CT - DEEP
A weighted average of composition percents was used when the findings for small segments of the waste stream were aggregated to describe a larger piece of the waste stream. The weighted average for an aggregated composition estimate was performed as follows:
O p r p r p rj j j j 1 1 2 2 3 3* ( * ) ( * ) ...
where:
p = the proportion of tonnage contributed by the noted substream (i.e., the weighting factor)
r = ratio of component weight to total waste weight in the noted substream (i.e., the composition percent
for the given material component)
for j = 1 to m
where m = number of material components
The variance of the weighted average was calculated:
VarO p V p V p Vj r r rj j j ( * ) ( * ) ( * ) ...1

3. STATEWIDE WASTE CHARACTERIZATION RESULTS
3.1 STATEWIDE AGGREGATE MSW COMPOSITION
Figure 3-1 shows the composition and tonnage of disposed wastes in 2015, aggregating the Residential and ICI generator sectors. As shown, Paper and Food Waste are the most common material groups.
Figure 3-1 Municipal Solid Waste Composition and Quantities Disposed (tons)
Figure 3-2 compares the composition in 2015 with the same result from the 2010 Study. The most noteworthy change in the waste stream since 2010 is the heightened fraction of Food Waste remaining in disposed wastes, along with relatively lower incidence of most other materials. This will be discussed in more detail in the Residential and ICI results sections later in this chapter. It should be noted that when data are presented in percentages, a significant change in the percent of one fraction of the waste stream automatically results in a change in the percentages of all other materials. For example, the large increase in food waste drives down the percentage composition of other materials.

3. STATEWIDE WASTE CHARACTERIZATION RESULTS
CT - DEEP 3-3
The fraction of targeted curbside recyclables – dry fiber and plastic, metal and glass containers – remaining in the waste stream is a relatively small piece of the pie at a combined 15.9 percent.
Compostable organics – which include food wastes, green wastes, and some compostable papers – are quite significant at 41.4 percent. However, it is important to note that these materials may not be easily source- separated prior to disposal, nor separated from disposed wastes such that they could be recovered for feedstock in a plant designed to manage organic wastes.
Even with significantly enhanced capture of targeted fiber, recyclable containers, and organics, over 41 percent of the disposed waste stream is not readily recyclable in existing curbside (or on-site commercial) recycling programs without:
Adding materials to the existing programs,
Making better use of other outlets for diverting materials (home composting, scrap metal recyclers, reuse stores, etc.)
Adding new recycling programs possibly in conjunction with development of local markets to accept such materials.
It is also critical to note that the above figure represents the rosiest possible definition of what is “recoverable” in existing programs. Manual sorters were trained to separate all items for placement in the correct category, and did not make any adjustments for contamination of sorted materials, nor the ability of a mechanical processing system to accurately separate such materials for recovery. The results of this exercise can be considered an “academic” characterization of the wastes stream. Many of the recyclable and compostable organic items would never be recovered or diverted because of contamination, or because they are so intermingled with non-recoverable items prior to placement in the waste receptacle (or as a result of the collection process) that no processing line could economically separate and recover the item.

Figure 3-4 shows the top 10 most prevalent materials in the MSW stream in both the 2010 and 2015 Studies. As shown, the most prevalent material in both studies was Food Waste and Compostable Paper, although the incidence of both has increased in 2015.
Figure 3-4 Comparison of 2015 and 2010 Top 10 Materials
Table 3-1 on the following page provides a detailed statistical profile of the 2015 statewide aggregate disposed waste stream. For each material category, the mean percent, confidence intervals, and estimated tonnage are shown.
Confidence intervals are calculated at a 90 percent level of confidence. It should be noted that the sum of the mean percentages for all of the individual materials within a material group sum to the mean percentage shown for the group. For example, the sum of all of the paper materials is the same as the 23.1 percent shown for Paper as a material group. However, the same does not hold true for the confidence intervals. Confidence intervals are calculated individually for each row in this table; the sum of the confidence intervals for each individual material will not equal the confidence interval for the material group as a whole.

3.1.1 FOOD WASTE IN PACKAGING
DEEP recognized that a significant fraction of food is discarded while still contained in packaging, and that this still-packaged food waste may be problematic for some processors. Given the heightened interest in the state at the current time in developing anaerobic digestion, composting, and other organics recovery facilities in an attempt to increase diversion of organics, DEEP requested a closer analysis of food wastes.
In an effort to investigate the constraints of separating food, the 2015 Study attempted to differentiate between (a) packaged food from (b) food that is loose in the sample or is contained in a bag, box or other

container for disposal. Packaged food includes food that is remaining in its factory or retail packaging, including jars, cans, clamshells, flexible packaging, and any other packaging.
Table 3-3 summarizes the observed split between food that was found loose in the waste stream compared to food that was discarded while still substantially contained in some form of packaging. Presumably the 12.4 percent of disposed food waste still contained in packaging would either not be available for capture in many organics recovery systems, or else might diminish the performance of such systems.

It is critical to note that this study did not include food discarded in film plastic bags (including garbage bags) as being “contained in packaging.” The manual sorting process for waste characterization studies is very effective at fully separating food from all packaging and other materials – much more so than a mechanical processing line would be expected to perform. Any processing system that is intending to accept mixed wastes should expect to encounter a significantly higher fraction of food wastes that are not easily separable without substantial resources devoted to the task.
3.1.2 FLEXIBLE FILM PACKAGING
DEEP also specified film pouches and other hard-to-recycle films as a material type of interest. Flexible Film Packaging was defined in this study as:
Plastic film packaging that is multi-layered (laminated) with multiple resins, sometimes with flat bottoms allowing pouch to stand on its own. May contain non-plastic foil layers and "tie-layers" that bond or fuse different layers together. Mostly used for preserving food. Examples include coffee bags, juice pouches, wine pouches, baby food, and some soap or detergent pouches.
Significant growth in the use of flexible film packaging has been widely reported, due to its attractive lifecycle environmental and economic profile. The 2015 Study tested the incidence of flexible film packaging on the disposed waste stream.
Summary data are shown in Table 3-4. As shown in this table, flexible film packaging was found to be almost negligible in the disposed waste stream, at approximately 0.2% and just over 4,000 tons statewide. Of particular interest, flexible film packaging makes up only 1.5 percent of all plastics in disposed wastes. Given that one of the primary objectives of flexible film packaging is to greatly reduce the weight associated with transporting packaged food and other goods, it is perhaps not surprising that this type of packaging makes up such a small fraction of the waste stream.

3.2 STATEWIDE RESIDENTIAL WASTE COMPOSITION
Figure 3-5 shows the composition and tonnage of Residential wastes in 2015. As shown, Paper and Food Waste are the most common material groups, although significant contributions come from Other Wastes, Other Organics, C&D Debris and Plastics.
Figure 3-5 2015 Residential Waste Composition and Disposed Quantities (tons)
Figure 3-6 compares the composition of Residential waste in 2015 with the same result from the 2010 Study. Although it was beyond the scope of this study to determine the causes of observed changes in the waste stream, these findings suggest that expansion of curbside single stream recycling has successfully reduced the incidence of targeted recyclables in the disposed waste stream. A side effect of increased recycling – observed in many other waste characterization studies that have been updated in the past three years – is that the percentage of Food Waste, C&D Debris, and Other wastes is significantly higher as targeted recyclables are removed from the stream.

Figure 3-7 below shows the mean percentage of recoverable materials in the residential waste stream. The “Not Currently Recoverable” portion includes materials that are potentially recoverable, but are not targeted in residential single stream recycling programs. Readers are encouraged to review the discussion surrounding Figure 3-3 for additional consideration about how to interpret the data in Figure 3-7.
Figure 3-7 Recoverability of Residential Wastes in Existing Curbside Programs
Figure 3-8 compares the top ten most prevalent materials in the 2015 and 2010 Studies. This figure highlights the significant increase in the contribution of food waste. This figure also shows a significant reduction in Leaves and Grass; it must be noted that some of this difference may be attributable to the different seasons in which sorting was performed in each Study, and whether heavy generation of grass clippings (spring) and leaves (fall) were or were not captured during the sampling periods.

Table 3-5 provides a detailed statistical profile of the statewide disposed Residential waste stream.
Table 3-5 Detailed Residential Waste Composition
The following observations can be made about the results in Table 3-5:
Curbside Recycling: The incidence of recyclable paper (including OCC) and containers is relatively low, suggesting that the curbside programs that have been implemented in Connecticut have made an impact at diverting these materials from disposal.
Diversity of Plastic Waste: The diversity of plastic resins, packaging types, durable product types, and overall uses remains high as in the 2010 Study.
Food Waste: Food waste is the most significant material in the residential waste stream, by weight, with most of the food being disposed after removal from its original packaging (although often re-

C&D Debris: A meaningful fraction of C&D debris, mostly associated with home renovation projects, is disposed in residential waste.
Electronic Waste: There was very little electronic waste, suggesting that programs available to divert these materials are successful keeping them out of landfills.
HHW: Similarly, the incidence of HHW is quite low, with much of this group attributable to the empty HHW containers which contain a significant amount of the weight.
Compostability of Other Organics: Although this category is significant, only the green waste categories are compostable. It is not clear if the seasonality of sampling events impacted the incidence of these green waste categories.
Problem Materials: There are still a number of materials that are commonly disposed that cannot be readily diverted. These include Diapers and Sanitary Products, Treated Wood, Fines, and a number of “remainder and composite” (catch-all) categories.

3.3 STATEWIDE ICI WASTE COMPOSITION
Figure 3-9 shows the composition and tonnage of ICI wastes in 2015. As shown, Paper and Food Waste are the most common material groups in the ICI stream.
Figure 3-9 ICI Waste Composition
Figure 3-10 compares the composition of ICI waste in 2015 with the same result from the 2010 Study. Once again, there is an increased incidence of Food Waste. The magnitude of the increase in Food Waste tonnage cannot be readily explained in the absence of a better understanding of changes in waste generation, collection, and processing dynamics at the five host facilities since the 2010 Study. Such changes in these dynamics are also suggested by the decrease in C&D. Ultimately, it was beyond the scope of this study to pinpoint the causes of the observed change in disposed Food Waste and C&D at the host disposal facilities in the 2015 Study.

Figure 3-11 below shows the mean percentage of recoverable materials in the ICI waste stream. The “Not Currently Recoverable” portion includes materials that are potentially recoverable, but are not targeted in a typical single stream recycling programs. Readers are encouraged to review the discussion surrounding Figure 3-3 for additional consideration about how to interpret the data in Figure 3-11.
Figure 3-11 Recoverability of ICI Wastes in Existing Single Stream Programs
Figure 3-12 compares the top ten most prevalent ICI materials in the 2015 and 2010 Studies. This figure highlights the significant increase in the contribution of both food waste and compostable paper. The most common materials remained fairly consistent between the two studies.

3.4 COMPARISON BY GENERATOR SECTOR
Figure 3-13 compares the percentage composition of material groups for Residential and ICI waste. On a percentage basis, it is shown that ICI waste contains a higher incidence of Paper and Food Waste, while the Residential sector disposes a higher percentage of Other Organics (which include yard debris and diapers) and Other Wastes.
Figure 3-13 Comparison of Waste Composition by Generator Sector
Figure 3-14 shows the same results, instead displaying the tonnage of materials disposed. Because of the estimated split between Residential and Commercial tons, the absolute quantity of both Paper and Food Waste is comparable in both generator sectors.

3.5 RESULTS BY DEMOGRAPHIC REGION
The following subsections provide detailed statistical results for Residential and ICI wastes from the Urban, Suburban and Rural regions of the state.
Table 3-10 provides a count of the number of samples obtained for each combination of generator sector and demographic origin.
Table 3-10 Urban, Suburban and Rural Waste Sample Counts

ICI
Samples
Total
Samples
Urban 114 78 192
Suburban 11 10 21
Rural 10 12 22
Total 135 100 235
As shown in the table, the majority of samples were found (through scalehouse personnel and driver interviews) to have originated in cities or towns classified as Urban based on their population density. This exercise confirms that the statewide aggregate results presented in this report are heavily weighted toward Urban areas of the state, and future studies may want to increase sampling from Suburban and Rural areas.
Also because of the relatively small samples size for Suburban and Rural wastes, the composition estimates for these two demographic regions exhibit lower certainty (i.e., wider confidence intervals) compared to the results from Urban areas. It is therefore less meaningful to rigorously compare the results across demographic regions.
Finally, no data are available to use as weighting factors to aggregate Residential and ICI waste within each demographic stratum. Because of these reasons, this report presents the tabular results separately for Residential and ICI waste within each demographic region, but does not aggregate waste composition by demographic stratum or attempt to compare the results.

4. SINGLE STREAM RECYCLING RESULTS
4.1 AGGREGATE SINGLE STREAM RECYCLING COMPOSITION
The results in this section combine all 81 samples of residential single stream recyclables to generate the average composition of these recyclables.
4.1.1 COMPOSITION WITH BAGGED WASTE CONSIDERED A CONTAMINANT
The sorting protocol for single stream recyclables included a category for Bagged Wastes. The results below treat bagged waste as if 100 percent of the material in the bags were non-targeted materials, i.e., contamination. Newspapers that have not been removed from the sleeves are also considered non-recyclable in these figures.
Figure 4-1 illustrates the breakdown of recyclable paper (blue), recyclable containers and plastics (green) and contamination (red) in single stream recycling. Recyclable containers comprise just over 27 percent of the total, with glass bottles (including broken glass) the most prevalent container type by weight.

Figure 4-2 presents the 10 most prevalent individual material categories found in single stream recyclables. Eight of the top 10 items are materials that are actively targeted in single stream programs. Non-recyclable Paper (including Newspapers in sleeves) and Bagged Waste made the top 10 list as contaminants, confirming what is often reported anecdotally by MRF operators.

4.1.2 BAGGED WASTE COMPOSITION
Bagged wastes were subsequently analyzed to determine what materials are arriving at single stream MRFs still contained in bags. Figure 4-3 shows the incidence of both targeted recyclables and contaminants in bagged wastes. As shown, bagged wastes were found to be roughly split between trash and recyclables. In practice, some bags contained mostly or entirely recyclables, while other contained mostly or entirely trash. Other bags contained a mix.

4.1.3 COMPOSITION WITH BAGGED WASTE SORTED TO PROPER CATEGORY
The composition of single stream recyclables has been restated in this section to reflect the impact of breaking open and sorting the bagged wastes into the appropriate category. Figure 4-4 restates the breakdown of recyclable paper, recyclable containers/plastics, and contamination. As shown, the overall contamination rate drops slightly to 16.7 percent (with bagged newspaper still considered “contamination”). If bagged newspapers are considered acceptable, then the contamination rate drops to 15.2 percent.

4.2 SINGLE STREAM COMPOSITION BY MRF
Single stream samples from each host MRF were analyzed separately to investigate differences in the inbound material. Figure 4-5 shows this comparison for the case where bagged wastes and newspapers still in the sleeve are considered to be contaminants. As shown, the two MRFs are receiving a relatively comparable mix of inbound material.

4.3 ANALYSIS OF DEPOSIT CONTAINERS
Connecticut’s beverage container deposit law targets beer, carbonated soft drinks, and water. These beverage types are packaged in PET plastic bottles, aluminum cans, and glass bottles. The 2015 Study include separate categories for Connecticut deposit bottles and cans as well as non-deposit categories of PET plastic, aluminum and glass. Table 4-5 summarizes the data focusing on Connecticut deposit containers.

4. SINGLE STREAM RECYCLING RESULTS
CT - DEEP 4-11
The following observations are made about deposit containers in the disposed waste stream and in single stream recyclables:
The majority of PET bottles/jars and glass bottles/jars being placed in the disposed waste and single stream are non-deposit containers. This suggests that a significant fraction of PET and glass deposit containers are being redeemed through normal channels within the state. It also may suggest that there are many other types of non-carbonated beverages and non-beverage products being packaged in PET bottles and glass jars. It was beyond the scope of this study to investigate the universe of deposit container recycling.
By weight, deposit containers make up only 0.8 percent of disposed wastes, but this projects to over 17,600 tons of deposit containers that are nonetheless still being disposed.
Deposit containers were found to be 3.0 percent of single stream recyclables.1
Just over half of the aluminum cans found in both the disposed waste stream and in single stream recyclables were deposit containers. While this may seem like a high fraction, it nonetheless suggests that aluminum cans are being redeemed at a reasonably high level. This conclusion is inferred because the vast majority of aluminum cans sold in the market contain carbonated beverages (beer and soda). Non-deposit aluminum cans include primarily juices and aluminum cat food tins (which were included with non-deposit aluminum cans by definition for this study).
It was beyond the scope of this study to analyze the overall performance of the deposit system, and several statements above may warrant further investigation.
1 No tonnage data for single stream recyclables was available for inclusion in this report.

5.1 OVERVIEW
The 2015 Study analyzed disposed wastes from six ICI generator types:
Grocery Stores,
Restaurants,
Hotels,
Retail Big Box Stores,
Small Retail Stores, and
Offices.
This chapter contains disposed waste composition profiles for these six generators. For each generator type, the top five most prevalent disposed waste categories are shown, along with a detailed statistical profile of the disposed wastes.
It is important to note that the results contained herein, while indicative of the differences in waste composition across various ICI generator types, are based on limited sampling (in some cases very limited) and it is possible that a more comprehensive study would find materially different results.
5.2 ICI GENERATOR RESULTS: GROCERY STORES
A total of nine samples were obtained from Grocery Stores. Figure 5-1 shows the most prevalent materials in Grocery waste, which cumulatively make up 84.0 percent of wastes from this generator. Although not shown in the table, roughly 13.5 percent of Food Waste was contained in packaging.

5.4 ICI GENERATOR RESULTS: HOTELS
Only two samples were obtained from Hotels, so it is not possible to make judgements on the representativeness of the reported data. Figure 5-5 shows the most prevalent materials in Hotel waste, which cumulatively make up 65.1 percent of wastes from this generator.
Figure 5-5 Top 5 Most Prevalent Constituents in Hotel Waste
Figure 5-6 shows the incidence of routinely recycled materials (corrugated cardboard, fiber, bottles and cans) as well as compostable organic materials (primarily food waste and low grade paper). Hotel waste appears to have comparable divertibility with the overall ICI waste stream, although with significantly more recyclable containers.

5.5 ICI GENERATOR RESULTS: RETAIL BIG BOX STORES
Only three samples were obtained from Retail Big Box stores, so it is not possible to make judgements on the representativeness of the reported data. Figure 5-7 shows the most prevalent materials in Retail Big Box waste, which cumulatively make up about 61 percent of wastes from this generator. Interestingly, significant amounts of corrugated cardboard were found in these samples. Additionally, one sample contained a sizeable amount of compressed fuel cylinders, which is likely skewing the results given that only three samples were obtained.

6. CONCLUSIONS & RECOMMENDATIONS
6.1 CONCLUSIONS
Comparability: The disposed waste composition found in the 2015 Study can be closely compared to the results of the 2010 Study. With the exception of a difference in seasonality of data collection, the sampling plan and field data collection methods remain largely unchanged.
Dwindling Incidence of Curbside Recyclables: The results of this study (as well as other studies that have been performed nationally) show that the incidence of recyclable fibers and containers continues to diminish in the disposed waste stream. In the case of fibers, this is probably due to a combination of factors beyond just an increase in recycling (i.e., reductions in paper production). Regardless of the cause, it appears that the incidence of recyclable fiber and containers in disposed waste continues to decrease, and that the expansion of curbside recycling program (especially single stream) contributes to this.
Food Waste in Packaging: This study made a first attempt at determining the fraction of food that is still contained in packaging when disposed. Although this study found that only 12.4 percent of all disposed food was still in its factory or retail packaging, the proportion of food waste that was wrapped in plastic films is significantly higher (although was not measured in this study).
Opportunity for Diversion of Organics: The data are clear in identifying food waste, green waste and low grade compostable papers as being a significant fraction in the disposed waste stream. While this will entice many to push for aggressive diversion of these materials, is should be noted that the food waste and compostable papers may be more difficult to separate and recover than these results might suggest. Mechanical and optical sorting capabilities are not able to achieve the level of accuracy of the manual sorting that occurred in this study.
Flexible Film Packaging: This study found that the weight of flexible film packaging in the disposed waste stream is negligible.
Single Stream Recyclables Composition: This study provides a first comprehensive look at the composition of inbound single stream recyclables. Given that this data has not been in the public domain previously, it will be important for recycling industry stakeholders – especially other MRF operators – to review and comment on the reasonableness of the data. Furthermore, it should be cautioned that the results shown here are very specifically for residential curbside single stream recyclables; any MRF that is also processing residential drop-off, multi-family, or commercial materials together with residential single stream may not find the same incidence of targeted recyclables and contamination.
Demographic Influence: The assignment of samples as being urban, suburban and rural confirms that the statewide aggregate results presented in this report (and in the 2010 Study) are heavily weighted toward urban areas of the state. Relatively few suburban or rural samples were captured.
ICI Generator Data: The ICI generator-specific data were captured to test the differences in ICI waste from several well-known, easily defined generator types. As expected, disposed wastes varied dramatically across ICI generators. This confirms that diversion programs need to be customized for individual industries (and, extending that logic) to individual businesses and institutions in order to maximize diversion from such entities.
6.2 RECOMMENDATIONS
Continue Performing Statewide Studies: Statewide studies both inform about the overall disposed waste stream for state-level planners, and also provide data to municipal and private solid waste and recycling stakeholders for a variety of uses. The CT DEEP joins state agencies from roughly a dozen

other states at conducting statewide waste characterization analyses on a regular basis, and should continue to perform a similar project over five to seven year intervals.
Consider Statewide Disposal Facility Gate Survey: Although the use of the same five host disposal facilities is believed to assure consistency in the results of the 2015 Study compared to the 2010 Study, expanding waste characterization research to other facilities may be valuable. In particular, it may be highly informative to conduct hauler surveys at other disposal facilities to build a better understanding of the breakdown of residential and ICI waste. (Of course, this can only be completed with cooperation from facility owners, many of which are private and may opt not to participate in such research if it risks divulging sensitive customer data.)
Expand Analysis of Recycling Characterization: No tonnage data was included in this study, nor was any attempt to calculate the capture rate (or recovery rate) for commonly targeted single stream recyclables. While it may be difficult to compile the underlying data needed to make this calculation (which includes container redemptions as well as estimates of the quantity of single stream materials collected in the state), the results would be extremely useful to stakeholders attempting to understand the success of current programs. This could be accomplished by funding recovery rate analyses in representative communities and routes in between the waste characterization studies.
Perform a Mass-Balance MRF Audit: The single stream analysis performed in this study followed conventional grab sampling methods. Should the results of this method encounter criticism, it may be worthwhile for DEEP to engage a MRF owner as a partner and to conduct a mass-balance test of inbound composition. Under this alternative MRF auditing approach, the MRF operator makes arrangements to shut down the MRF and clean/empty all bunkers and hoppers; accumulate 50 to 100 tons of single stream material over a period of several days or a week; and then run the accumulated material through the process line to be sorted via normal processes. Once the accumulated recyclables are processed, the MRF must be shut down again to analyze the composition of each sorted commodity and residue, such that inbound material composition can be calculated.
Investigate Stakeholder Interest to Expand ICI Generator Sampling: The six ICI generator types were selected based on input from DEEP and other stakeholders. However, with additional lead time, it may be possible to recruit support from other industries or institutions (e.g., public schools) to participate in generator-specific sampling and sorting in future studies.
Expand Analysis of State Reported Disposal: In future studies, it may be worth expanding the analysis of facility-level disposal reports to see if any changes to the sampling plan are identified. Although this exercise may suggest enhancements for getting more representative results, doing so may reduce comparability with prior studies insofar as different facilities could be hosting field data collection.
Add More Host Facilities: The 2015 Study included single stream recyclables for the first time. It duplicated the same five host disposal facilities as the 2010 Study, which are weighted toward Urban areas of the state. Consider expanding the study to other disposal and recycling facilities, especially to capture more samples from suburban and rural areas of the state.
Expand Analysis to Capture Higher Heating Value: Given that Connecticut relies so heavily on RRFs, it may be worthwhile to begin estimating Btu value of the disposed waste stream. If fiber and plastics are being light weighted and diverted, and if organics (especially food waste) is what remains, what impact does this have on the Btu value of the waste stream?
Consider More Detailed Analysis of Organic Wastes: Because of the interest in capturing energy from organic wastes and/or increasing composting of organics it would be useful to expand the categories of sampling to specifically address what percent of food waste (especially) is contaminated by packaging. This can be critical to the success of organics processing facilities.

The U.S. Census Bureau classifies as Urban all territory, population, and housing units located within
urbanized areas (UAs) and urban clusters (UCs). It delineates UA and UC boundaries to encompass
densely settled territory, which generally consists of:
w A cluster of one or more block groups or census blocks each of which has a population density of at
least 1,000 people per square mile at the time, and
w Surrounding block groups and census blocks each of which has a population density of at least 500
people per square mile at the time, and
w Less densely settled blocks that form enclaves or indentations, or are used to connect discontiguous
areas with qualifying densities.
Rural consists of all territory, population, and housing units located outside of UAs and UCs.
Geographic entities, such as metropolitan areas, counties, minor civil divisions (MCDs), and places, often
contain both Urban and Rural territory, population, and housing units.
